 * I installed WMPL and made my page multilingual. Since then, I get the following
   emails after a payment was made (also the payment seems to be successfully).
 * “Bei einer Webhook Anfrage ist ein Fehler aufgetreten. Hier finden Sie die Details:
   [https://<mypage&gt](https://<mypage&gt);.payrexx.com/cadmin/index.php?cmd=checkout&
   act=api&tpl=webhookLogs&id=…..”
 * With debug in wordpress on, I get the following error on the api page
 * [https://www.nussfee.ch/?wc-api=wc_payrexx_gateway](https://www.nussfee.ch/?wc-api=wc_payrexx_gateway)
 * DEBUG output:
    ”

 * Hi the issue was, that you used [https://nussfee.ch](https://nussfee.ch) as your
   Shop URL for the webhooks instead of [https://www.nussfee.ch](https://www.nussfee.ch)
   which was not correct anymore.
 * The new webhooks seem to work fine now.. Do you still need help?
 * Best regards Noah from payrexx
